Abstract

The invention discloses a sample preparation contracting dividing device, relates to the technical field of sample preparation of a coal sample, and can solve the technical problem of low running reliability of a contracting dividing device. The contracting dividing device in turn, from top to bottom, includes a distributing device, a contracting dividing funnel and a sample retention device; the distributing device includes a distributing device body with a conical surface peripheral surface, a plurality of diversion channels are arranged on the peripheral surface of the distributing device body, the diversion channels are from top to down obliquely arranged, the oblique direction is same, the distributing device body emptily sleeves a vertically-placed fixed shaft, the fixed shaft is in fixed connection with the contracting dividing funnel, the fixed shaft and the contracting dividing funnel are coaxial; the contracting dividing funnel is an inverted conical structure, and the side wall of the contracting dividing funnel is provided with a material dropping hole; and the sample preparation contracting dividing device is used for contracting dividing of a sample material.

Description

Technical field [0001] The invention relates to the technical field of coal sample preparation, in particular to a sample preparation shrinking device. Background technique [0002] In the process of preparing coal samples, reduction is a key step. The reduction is to reduce the amount of coal sample under the condition that the particle size of the coal sample remains unchanged, so as to reduce the follow-up workload and achieve the coal sample amount required for inspection. Under normal circumstances, the coal sample is reduced by a sample reduction device. [0003] The sample preparation reducing device includes a distributor, a reducing funnel, a sample retaining device, a driving motor and a transmission mechanism, etc., wherein the reducing funnel is provided with a blanking hole. When the sample preparation reducer is to reduce the coal sample, the drive motor drives the transmission mechanism to operate, and the transmission mechanism drives the reduction funnel to rotat...
